The Tantive IV was a starship used by the Rebel Alliance during the Galactic Civil War. It was used as a spy ship against the Empire, and was controlled by Princess Leia. During a mission to retrieve Obi-Wan Kenobi from Tatooine, the Tantive IV was attacked by Darth Vader's ship. Vader was searching for stolen plans that the Rebels had taken, plans for Vader's Giant Beach Ball which he had written himself in preperation for his beach party. The Tantive IV was raided by Stormtroopers who killed the crew and captured the Princess. However, the plans were no-where to be found. As it happened, R2-D2 had taken the plans and had made his way to Tatooine. Enraged, Vader destroyed the ship with his awesome 'I'm a bad guy' powers.
